Tampon with clean appearance post use

ABSTRACT

A catamenial tampon comprises a compressed absorbent member having an inner region and an exterior surface, the compressed absorbent member comprising an absorbent material. An overwrap substantially covers the exterior surface of the compressed absorbent member. The overwrap comprises an apertured fluid pervious material that is hydrophobic or rendered hydrophobic relative to the compressed absorbent member. The fluid pervious overwrap therefore tends to remain free of fluid as the fluid is preferentially partitioned into the absorbent member.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. Ser. No. 10/653,836, filedSep. 3, 2003, which claims the benefit of U.S. Provisional ApplicationNo. 60/408,455, filed Sep. 5, 2002.

FIELD OF THE INVENTION

This invention relates to an improved absorbent catamenial tampon havingimproved appearance after use.

BACKGROUND OF THE INVENTION

A wide variety of absorbent catamenial tampons have long been known inthe art. While it has been found that these tampons perform theirintended function well, the post use appearance of these tampons canhave a negative impact on the user. Until recently it was notappreciated that the visual impact on the user of the post-use tamponwas an important design criteria for tampons. In fact, it has beendiscovered that the post-use appearance is an important factor toconsider in affecting the user's total use experience.

Accordingly, it would be beneficial to have a tampon that provides animproved visual appearance after use.

Further, it would be beneficial to have a tampon that, in addition toproviding an improved appearance.

Finally, it would be beneficial to provide a tampon that can provide animproved appearance after use, and is economical to produce.

SUMMARY OF THE INVENTION

A catamenial tampon is disclosed. The tampon comprises a compressedabsorbent member having an inner region and an exterior surface, thecompressed absorbent member comprising an absorbent material. Anoverwrap substantially covers the exterior surface of the compressedabsorbent member. The overwrap comprises an apertured fluid perviousmaterial that is hydrophobic or rendered hydrophobic relative to thecompressed absorbent member. The fluid pervious overwrap therefore tendsto remain free of fluid as the fluid is preferentially partitioned intothe absorbent member.

Apertures in the overwrap contribute to better fluid acquisition offluid, including viscous fluid components of menses, by providingunimpeded fluid pathways to and into the absorbent member. By providingfor preferential fluid paths into the absorbent member, the overwrap canremain relatively free of fluid, particularly viscous fluid, or fluidhaving solids components, again, such as menses. Therefore, the fluidpervious, apertured overwrap contributes to an overall cleaner post-useappearance.

BRIEF DESCRIPTION OF THE DRAWINGS

While the specification concludes with claims particularly pointing outand distinctly claiming the subject matter that is regarded as formingthe present invention, it is believed that the invention will be betterunderstood from the following description taken in conjunction with theaccompanying drawings, in which:

FIG. 1 is a perspective view of a tampon of the present inventionincorporating a compressed absorbent member and fluid pervious overwrapcovering the exterior surface.

FIG. 2 is a plan view the assembled absorbent material and fluidpervious overwrap prior

to compression.

DETAILED DESCRIPTION OF THE INVENTION

The present invention comprises a fluid pervious overwrap that coversthe exterior surface of a compressed absorbent member and which exhibitsimproved visual appearance after use. The overwrap can substantiallypermeate the folds and interstices, i.e., an inner region, of thecompressed absorbent member and, as well, can extend beyond thewithdrawal end to form a skirt.

The fluid pervious overwrap can comprise a fibrous nonwoven material. Inone embodiment the nonwoven material can be apertured. The nonwovenmaterial can comprise natural fibers, synthetic fibers, or a blend ofsynthetic and natural fibers that permit fluid to pass through to anabsorbent member. The nonwoven material can be hydrophilic orhydrophobic. In a preferred embodiment, the nonwoven material ishydrophobic, or rendered hydrophobic.

The fluid pervious material can be used as is, or it can be apertured bymethods known in the art to be an apertured, fluid pervious material.Apertures permit relatively viscous fluid, or fluid having some solidscontent, such as menses, to pass relatively unimpeded through the fluidpervious material such that it can be readily absorbed by the absorbentmember. The apertures permit the fluid, such as menses, to penetratedeeper into the article to improve the masking property of the article.This is believed to be due to the absorbed fluid being offset a certaindistance from the surface of the overwrap.

Therefore, the fluid pervious, preferably nonwoven, overwrap of thepresent invention permits fluid absorption into the compressed absorbentmember. As well, in a preferred embodiment the fluid pervious overwrapis hydrophobic, or rendered hydrophobic, such that absorbed fluid isattracted to, and remains in, the absorbent member, not in the overwrap.Because of the relatively poor wicking propensity of the hydrophobicoverwrap, the overwrap remains relatively free of menses, giving acleaner visual appearance to the post-use article. In one embodiment,apertures provide for improved fluid flow into the core, and bettervisual appearance post use. By providing apertures in the overwrap,fluid absorption of relatively viscous fluid can be enhanced due to thelack of any obstruction to fluid absorption via the apertures. Post-use,the absorbent member is visible through the apertures and appears red.The overwrap remains relatively free of menses, and appears less soiledand closer to its original appearance. This gives the appearance of“deep down” menses storage, and overall cleanliness.

As used herein the term “tampon” refers to any type of absorbentstructure that is inserted into the vaginal canal for the absorption offluid therefrom. Typically, tampons are constructed from an absorbentmaterial that has been compressed into a vaginally insertable shape.

As used herein the terms “pledget” or “tampon pledget” are intended tobe interchangeable and refer to a construction of absorbent materialprior to the compression of such construction into a tampon.

As used herein the terms “vaginal cavity,” “within the vagina” and“vaginal interior,” are intended to be synonymous and refer to theinternal genitalia of the human female in the pudendal region of thebody. The term “vaginal cavity” as used herein is intended to refer tothe space located between the introitus of the vagina (sometimesreferred to as the sphincter of the vagina) and the cervix and is notintended to include the interlabial space, including the floor ofvestibule. The externally visible genitalia generally is not includedwithin the term “vaginal cavity” as used herein.

As used herein “fluid pervious” refers to the properly of a material andis characterized by the ability to carry fluid or moisture, such as bycapillary action, prior to any post-processing step, such as aperturing.Therefore, for example, an untreated woven or nonwoven material is fluidpervious and a thermoplastic film is not. A nonwoven permits fluid flowvia the interstices between fibers, such that fluid can flow through,either by capillary action and/or via a pressure differential from oneside of the nonwoven to the other such as the pressure experienced by atampon in use.

As used herein “aperture” refers to a macroscopic opening or “hole” asdistinct from inherent pores or interstices of fluid pervious materials,such as foams or nonwoven materials, for example. A macroscopic openingis visibly distinct to the naked eye of an observer having 20/20 visionat a distance of 45 cm.

As used herein “fluid pervious overwrap” refers to the fluid perviousmaterial covering the exterior surface of the compressed absorbentmember, as well as any interior surfaces or interior regions due to thefolding or rolling of the pledget prior to compression. The portion ofthe fluid pervious overwrap disposed in the folds of the compressedabsorbent member are said to substantially permeate the inner region ofthe compressed absorbent member. The fluid pervious overwrap cancomprise a fibrous nonwoven material comprising natural, synthetic, or ablend of natural and synthetic fibers. The synthetic fibers can includebut are not limited to fibers such as polyester, polyolefin, nylon,polypropylene, polyethylene, polyacrylic, cellulose acetate orbicomponent fibers. Natural fibers can include but are not limited torayon and those commonly known to be non-synthetic and of natural originsuch as cotton.

As used herein “hydrophilic” and “hydrophobic” have meanings as wellestablished in the art with respect to the contact angle of a drop ofwater on the surface of a material. Thus, a material having a contactangle of greater than about 75 degrees is considered hydrophobic, and amaterial having a contact angle of less than about 75 degrees isconsidered hydrophilic. Absolute values of hydrophobocity/hydrophilicityare not generally important, but relative values are. Thus, theabsorbent member of the tampon of the present invention is morehydrophilic than the overwrap, and the overwrap is more hydrophobic thanthe absorbent member.

As used herein the term “highly hydrophobic” refers to a material thathas, or is rendered to have, a contact angle of 90 degrees.

As used herein “compressed” refers to pressing or squeezing together tochange the size, shape, and/or volume to obtain a tampon having avaginally inserlable shape.

As used herein, “vaginally insertable shape” refers to the geometricalform of the absorbent tampon after compression. The tampon may becompressed into a generally cylindrical configuration in the radialdirection along the longitudinal and/or lateral axes, axially, or inboth the radial and axial directions. An example of a typical compressedtampon is one which is about 10-16 mm wide and about 30-55 mm longdepending on absorbency. While the tampon may be compressed into asubstantially cylindrical configuration, other shapes are possible.These may include shapes having a cross section that may be described asrectangular, triangular, trapezoidal, semi-circular, hourglass, or othersuitable shapes.

Unless specifically stated otherwise, as used herein a first material is“substantially covering” or “substantially covers” a second materialwhen the first material covers at least about 75%, typically at leastabout 90% of the surface area of the second material.

As used herein “substantially permeating” or “substantially permeates”refers to the manner in which the fluid pervious overwrap is positionedin relation to the inner region of the compressed absorbent member. Forexample, the fluid pervious overwrap can follow the spiral (in the caseof rolled) or serpentine (in the case of the folded) contours of acompressed absorbent member and thereby extends into the inner region ofsaid member along the interstices formed by the contours of the rolls orfolds positioned in relation to the inner region of the compressedabsorbent member. Any other compression method resulting in the fluidpervious overwrap similarly following the contours of the compressedabsorbent member within the inner region is also acceptable.

The term “joined” or “attached” as used herein, encompassesconfigurations in which a first element is directly secured to secondelement by affixing the first element directly to the second element;configurations in which the first element is indirectly secured to thesecond element by affixing the first element to intermediate member(s)which in turn are affixed to the second element; and configurations inwhich first element is integral with second element; i.e., first elementis essentially part of the second element.

The term “rolled” as used herein, is the configuration of the compressedabsorbent member after winding the absorbent material substantiallycovered by the fluid pervious overwrap in a spiral round and round uponitself.

The term “folded” as used herein, is the configuration of the compressedabsorbent member that may be incidental to lateral compaction of theabsorbent material substantially-covered by the overwrap or maypurposely occur prior to a compression step. Such a configuration isreadily recognizable, for example, when the absorbent material abruptlychanges direction such that one part of the absorbent material bends andlies over another part of the absorbent material.

As used herein, “cm” is centimeter, “mm” is millimeters, “ml” ismilliliters “g” is grams, “gsm” is grams per square meter, “sec” isseconds.

FIG. 1 shows one embodiment of an absorbent tampon 20 of the presentinvention. A compressed absorbent member 22 (sometimes referred to asthe “absorbent core”) of the tampon 20 has an exterior surface 26. Thecompressed absorbent member 22 has an inner region 24. The exteriorsurface 26 of the compressed absorbent member 22 is substantiallycovered by a fluid pervious overwrap 40. The fluid pervious overwrap 40can comprise a plurality of apertures 25 that permit improved fluid flowof viscous fluid to and into the compressed absorbent member 22. Thefluid pervious overwrap can also extend to provide a skirl portion 44.In one embodiment, the tampon 20 includes a withdrawal means 48, such asa string.

The fluid pervious overwrap 40 is hydrophobic relative to the compressedabsorbent member 22. Hydrophobicity can be inherent due to the materialproperties of the fluid pervious overwrap material, or the fluidpervious overwrap can be rendered hydrophobic by suitable treatment ofan otherwise hydrophilic material. For example, the fluid perviousoverwrap 40 can comprise a nonwoven web of conjugate fibers, such asbicomponent polyethylene/polypropylene fibers that are inherently morehydrophobic than the compressed absorbent member 22. Other hydrophobicfibers can also be used, such as bicomponent polyethylene/polyesterfibers.

If the fluid pervious overwrap 40 comprises a nonwoven web material ofhydrophilic fibers, such as rayon or a blend of rayon/cotton, thematerial can be rendered hydrophobic by a suitable treatment, such as acoating of a suitable material sufficient to render the fluid perviousoverwrap sufficiently hydrophobic. For example, surface treatments caninclude applied coatings of silicone, such as Dow Coming 108® silicone,available from the Dow Corning Co. Inc., Midland Mich.; or SucroseEsters of Fatty Acids (SEFA), available from the Procter & Gamble Co.,Inc., Cincinnati, Ohio, polyolefin waxes, or NALAN® available fromDuPont, Wilmington Del. Such coatings can render the fluid perviousoverwrap hydrophobic, or highly hydrophobic. The application of asuitable surface treatment can be achieved by spraying, slot coating,immersion and other methods known in the art. The amount of coaling canbe varied as needed to render the fluid pervious overwrap 40sufficiently hydrophobic relative to compressed absorbent member 22. Inone embodiment, a 1% by weight coating of SEFA was found to besufficient. Sufficient relative hydrophobicity is achieved when fluidsuch as menses is absorbed into the compressed absorbent member 22 inuse, and is sufficiently desorbed from the fluid pervious overwrap 40 soas to partition the fluid into the core and away from the overwrap.

FIG. 2 shows the absorbent tampon 20 in a flat-out configuration, priorto folding or rolling and compressing into the configuration shown inFIG. 1. Fluid pervious overwrap 40, shown in FIG. 2 as having a portionthat is apertured, substantially covers the absorbent material 28 andpreferably covers all of absorbent material 28. The absorbent material28 has a first surface 34 opposed to a second surface 36 and aninsertion end 38 opposed to a withdrawal end 42. The absorbent material28 has both a longitudinal axis and a transverse axis indicated by thelines marked “L” and “T” respectively. Because the fluid perviousoverwrap 40 can be wrapped in various configurations, the width (orlength) of fluid pervious overwrap 40 may vary. The dimensions of thefluid pervious overwrap 40 may be greater than, lesser than, or equal tothe dimensions of the longitudinal or transverse axes of the absorbentmaterial being wrapped.

At least a portion of, and preferably all of, both first surface 34 andopposed second surface 36 of the absorbent material 28 is covered byfluid pervious overwrap 40 prior to compressing into compressedabsorbent member 22. The fluid pervious overwrap can be positioned byfolding around the insertion end 38 of the absorbent material 28. Thefluid pervious overwrap can overlap at the region 32, for example. Theoverlapping portions in region 32 need not be sealed, partially sealed,or otherwise joined, although such joining can be done.

To form the compressed absorbent member 22, absorbent material 28 andfluid pervious overwrap 40 (shown in FIG. 2) is typically rolled orfolded, compressed and optionally heat conditioned in any suitableconventional manner. After rolling or folding and compression, aperturedfluid pervious overwrap 40 not only covers the exterior surface 26 ofcompressed absorbent member 22, but is also embedded in the interiorfolds of the compressed absorbent member 22. That is, the aperturedfluid pervious overwrap permeates the interior of the compressedabsorbent member 22.

The fluid pervious overwrap may be joined to the absorbent material byany variety of means. The fluid pervious overwrap may be joined toitself or to the absorbent material. For example, one portion of fluidpervious overwrap may be joined to an opposed portion of the fluidpervious overwrap or the absorbent member using any suitable adhesive orheat/pressure bonding means. Such adhesive may extend continuously alongthe length of attachment or it may be applied in a non-continuousfashion at discrete intervals. Heat bonding includes thermally bonding,fusion bonding, or any other suitable means known in the art for joiningsuch materials. Alternatively, the fluid pervious overwrap may be joinedto the absorbent material along with the withdrawal cord by stitching asshown in FIG 2. Such stitching may use natural or synthetic thread.

Fluid pervious overwrap 40 can be made by any number of knowntechniques, but is preferably an apertured nonwoven material. Thenonwoven material can be made by carding, mellblowing, spunbonding,spunlacing, air laying, and the like. Aperturing can be accomplished byany known method, such as by hydroentangling on a suitable formingscreen, such as, for example, the method described in U.S. Pat. No.3,025,585. Aperturing can also be accomplished by various processesinvolving bonding and stretching, such as those described in U.S. Pat.Nos. 3,949,127; 4,588,360; 5,873,868. In one embodiment, the aperturesare formed by forming a plurality of spaced, melt stabilized regions,and then ring-rolling the web to stretch the web and form apertures inthe melt stabilized regions, as described in U.S. Pat. Nos. 5,628,097and 5,916,661, both of which are hereby incorporated by referenceherein. In another embodiment, apertures can be formed in a multilayeroverwrap by the method described in U.S. patent application Ser. No.09/886730 filed Jun. 21, 2001 in the name of Curro et al. and which ishereby incorporated herein by reference. In such a multilayer overwrapthe outermost layer can be hydrophobic while the innermost layer can behydrophilic. Other combinations of layers having various propertiesbeneficial to the use of the overwrap can be made as desired.

Apertures 25 can be of virtually any shape and size, as long as theoverwrap can provide the function of covering the absorbent member afterin-use expansion, and provide for a masking effect after use. In apreferred embodiment, apertures 25 are generally round or oblong shaped,in a regular pattern of spaced apart openings. The apertures can eachhave a diameter of from 0.5 to 2 mm, preferably about 1 mm, and can forman open area of between 1% and 25%, preferably between 2% and 20%, mostpreferably between about 10% and 15%. It is believed that the benefitsof the present invention can be realized with non-repealing and/ornon-regular patterns of apertures having various shapes and sizes.

The basis weight of the nonwoven overwrap prior to forming apertures canbe from about 10 to about 60 grams per square meter (gsm), alternativelyfrom about 15 to about 30 gsm. Synthetic fibers, if used, may havehydrophobic and/or hydrophilic finishes, although, as mentioned above,the fibers of the nonwoven are preferably rendered hydrophobic relativeto the absorbent member.

Therefore, in one embodiment, the present invention can be described asa catamenial tampon comprising a compressed absorbent member 22 havingan inner region 24 and an exterior surface 26, the compressed absorbentmember comprising an absorbent material. A fluid pervious overwrapsubstantially covers the exterior surface of the compressed absorbentmember. The overwrap comprises a material that is hydrophobic orrendered hydrophobic relative to the compressed absorbent member.

In another embodiment, apertures 25 contribute to better fluidacquisition of viscous fluid components of menses by providing unimpededfluid pathways to and into the absorbent member 22. By providing forpreferential fluid paths into absorbent member 22, the overwrap 40 canremain relatively free of fluid, particularly viscous fluid, or fluidhaving solids components, again, such as menses. Therefore, the fluidpervious, apertured overwrap contributes to an overall cleaner post-useappearance.

Therefore, in one embodiment, the present invention can be described asa catamenial tampon comprising a compressed absorbent member 22 havingan inner region 24 and an exterior surface 26, the compressed absorbentmember comprising an absorbent material. An apertured fluid perviousoverwrap substantially covers the exterior surface of the compressedabsorbent member. The overwrap comprises a material that is hydrophobicor rendered hydrophobic relative to the compressed absorbent member.

The overwrap 44 is preferably biodegradable, or bio-disentegratable.Therefore, the fluid pervious overwrap 44 can comprise rayon, arayon/cotton blend, or a blend of rayon and contton with polymericfibers, as is known in the art for biodegradable nonwoven webs. Therayon or rayon/cotton blend is then treated as discussed above to behydrophobic.

The absorbent material 28 may be any suitable size and thicknesssuitable for compression into a tampon having a vaginally insertableshape. In the embodiment shown in FIG. 2, the absorbent material isgenerally square or rectangular, but other shapes such as trapezoidal,triangular, hemispherical, chevron and hourglass shaped are alsoacceptable. A typical size for absorbent material prior to compressioncan be from about 30 mm to about 100 mm in length and from about 30 mmto about 80 mm in width. The typical range for the overall basis weightof the absorbent material 28 is from about 150 gsm to about 1250 gsmdepending upon desired absorbent capacity.

The absorbent material may be a laminar structure comprised of integralor discrete layers. In other embodiments, the pad need not have alayered structure at all. The absorbent material may comprise a foldedstructure or may be rolled. The resulting compressed absorbent member 22of the tampon 20 may be constructed from a wide variety ofliquid-absorbing materials commonly used in absorbent articles such asrayon (including tri-lobal and conventional rayon fibers), cotton, orcomminuted wood pulp which is generally referred to as airfelt. Examplesof other suitable absorbent materials include creped cellulose wadding;meltblown polymers including coform; chemically stiffened, modified orcross-linked cellulosic fibers; synthetic fibers such as crimpedpolyester fibers; peat moss; foam; tissue including tissue wraps andtissue laminates; or any equivalent material or combinations ofmaterials, or mixtures of these.

Typical absorbent materials comprise cotton, rayon folded tissues, wovenmaterials, non-woven webs, synthetic and/or natural fibers or sheeting.The tampon and any component thereof may comprise a single material or acombination of materials. Additionally, superabsorbent materials, suchas super polymers or absorbent gelling and open-celled foams, materialsmay be incorporated into the tampon.

The materials for the tampon can be formed into a fabric, web, or battthat is suitable for use in the absorbent material by any suitableprocess such as airlaying, carding, wetlaying, hydroentangling, needlingor other known techniques.

Pressures and temperatures, suitable for compression are well known inthe art. Typically, the absorbent material and the fluid perviousoverwrap are compressed in the radial direction and optionally axiallyby any means well known in the art. While a variety of techniques areknown and acceptable for these purposes, a tampon compressor machineavailable from Hauni Machines, Richmond, Va., is suitable.

In one embodiment, the tampon of the present invention may comprise awithdrawal means. The withdrawal means could be joined to the tampon andgraspable by the user for removal after use. The withdrawal means may bejoined to at least the compressed absorbent member and extends beyondthe withdrawal end. Any of the withdrawal means currently known in theart, such as string, may be used as a suitable withdrawal mechanism. Inaddition, the withdrawal means can take on other forms such as a ribbon,loop, tab, or the like. The withdrawal means may be integral with theabsorbent material.

The withdrawal means may be attached in any suitable manner known in theart including sewing, adhesive attachment, or a combination of knownbonding methods. The withdrawal means may be joined to any suitablelocation on the tampon.

While several methods of making the tampon of the present inventionshould be apparent to one of skill in the art in light of the disclosureherein, following is a description of one method of making a tampon ofthe present invention.

The process for making a tampon comprises the steps of providing anabsorbent material 28 having a first surface opposed to a second surfaceand an insertion end opposed to a withdrawal end. An apertured fluidpervious overwrap 40 is wrapped or folded about absorbent material 28 tocover, or substantially cover, the first surface 34 and second surface36. The apertured fluid pervious overwrap can extend beyond thewithdrawal end of the absorbent material to form a skirt portion. Awithdrawal means 48 such as a string can attached, such as by stitching,to the absorbent material. The wrapped absorbent with a skirt is rolledor folded and/or compressed to form a compressed absorbent member 22having a vaginally insertable shape. Upon compression the fluid perviousoverwrap substantially covers the exterior surface of the compressedabsorbent member and permeates into the interstices of the inner regionof the compressed absorbent member.
